Thermo-Diffusion Effects of a Stagnation Point Flow in a Nanofluid with Convection using the Adomian Decomposition Method

Abstract

The Thermo-diffusion solution effects a stagnation point flow of a nanofluid with convection using. Adomian Decomposition Method (ADM) is presented. The Partial differential equation representing the problem was reduced to an ordinary differential equation by introducing some similarity transformation variables. The transformed equations were solved using the ADM and the results were compared with existing results in the literatures. There is a good agreement between the method and the existing one, which indicate reliability of the method. The physical parameters that occurred in the solutions such as magnetic parameter, thermal Grashof numbers, concentration Grashof numbers, nano Lewis number, velocity ratio, Prandtl number were varied to determine their respective effects. It was observed that when the wall velocity is higher than the free stream velocity ( A 1) , the fluid velocity drop and rises when velocity at free stream is higher than the wall velocity ( A 1)
